ELECTRICAL-MECHANICAL AMUSEMENT SIMULATOR WITH GRAVITATIONAL EFFECTS

Abstract: The movement simulator consists of a cabin (15) that rotates through the action of a servomotor (12), seeing that the cabin/servomotor set rests on an axle (xx') that has its rotation controlled by another servomotor (5) and the set formed by the cabin and the two servomotors rests on a third axle (zz') that also has its rotation controlled by a third servomotor (1) in a way that all the moving components of the simulator have unlimited rotation, i.e., even beyond 360 grades over its respective axles.

Description: DESCRIPTIVE REPORT of Invention Patent for ELECTRICAL- MECHANICAL AMUSEMENT SIMULATOR WITH GRAVITATIONAL EFFECTS The present invention is relative to a movement simulator with rotation around its three axles, affording rotation movements in any angle and direction, where the arc angles might have unlimited values The current electrical-mechanical simulators, that have movements, are limited because they use only two axles or because the rotation angle around the axles corresponds to an arc smaller than 360 grades. These restrictions limit the application of graphical/software programs and limit the real effects of the gravitational and centrifugal forces. The electrical-mechanical simulator described in this report provides a rotation around its three axles, in an individual or simultaneous way, simulating thus the more variegated rotation movements. This simulation will give gravitational, centrifugal, turbulence and other sensations to a person located inside a cabin. Its functioning is based on the use of servomotors that control the position and rotation of the axles. The simulator will be better understood through the detailed description in consonance with the figures numbered from 1 to 5 that go with and are part of this report: Figure 1 - that represents the longitudinal section of the simulator - shows the (zz') axle rotation subsystem composed of the servomotor (1), mechanical coupling (2), axial bearing (3), and the energizing system (4); it shows the (xx 1 ) axle rotation subsystem, constituted by a second servomotor (5), mechanical coupling (6), the radial bearing (7), and the energizing system (8); and it also shows the top view of the (yy') axle rotation subsystem. Figure 2 shows the (zz') axle rotation subsystem that has a fixing structure of the servomotor (1), of the mechanical coupling (2), of the axial bearing (3) and of the energizing system (4). The latter is responsible for the energy transmission to the (xx 1 ) and (yy 1 ) axles rotation subsystems. Figure 3 shows the (xx') axle rotation subsystem that has an arc structure inlaid to the mechanical coupling (2), constituted by the second servomotor (5), mechanical coupling (6), radial bearings (7) and by the energizing subsystem (8). The latter is responsible for the energy transmission to (yy') axle rotation subsystem. Figure 4 is relative to the (yy') axle rotation subsystem and the radial bearing (9), the belt (10) and the pulley (1 1) of the rotation movement transmission to the cabin(15). Figure 5 is relative to the (yy 1 ) axle rotation subsystem showing, in longitudinal section, the servomotor (12), the belt and pulley coupling (13) and the cabin energizing system (14). The previous programming of the movements, in a manual or computerized way, puts in action the servomotors that rotates everything which is coupled to its axle. If only one servomotor is put in action, the cabin components will have a circumferencial rotation movement in a plane perpendicular to the rotation axle. If two or three servomotors are put in action simultaneously, the movement of each cabin component is spherical. Combining the rotation direction and the angular velocity of the three axles, it is possible to simulate sensations of movements found in entertainment such as the "roller coaster", the "star war" and the "submarine". The simulator here described has industrial applicability in professional training with flight and vehicles simulators; it has also applicability in medicine and robotics. The simulator motorization is obtained by electrical-mechanical means, using servo-systems consisting of servo-controllers and servo-motors.
